The 19-year-old pop sensation had shared the drawings with her 73 million followers on the social media site as part of a “post a picture” trend.
Billie shared the sketches after fans asked her to post “a drawing you’re really proud of,” on Monday.
The teenage singer than shared a page from her sketchbook which featured a number of drawings of breasts.
She wrote alongside it: “These probably lol i love boobs.”
One of her fans later shared a couple of screenshots of Billie’s Instagram account in which it showed her followers had dropped from 73 million to 72.9 million.
They took to Twitter to share this and claim that Billie’s sketches may be to blame for the sudden mass unfollowing, though it may be just coincidence that the drop happened at this time.
The fan tweeted: “BYE NOT HER LOSING 100K CUZ OF BOOBS.”
They attached the two screenshots to show the fall in followers.
Billie decided to respond to this observation with her own thoughts on her Instagram Story, writing: “LMFAOOO y’all babies smh.”
The singer has not been afraid to hit back at her fans when she feels they are being critical of her appearance or her actions.
Before Christmas, Billie took to her Instagram Story to speak out after there were comments about her hairstyle, which sees her have neon green roots flowing into dark hair.
She wrote in response: “Stop making fun of me…I’m f**king making you an album”
Billie then lightened up a bit and teased: “I will not put it out if you keep making fun of my hair. Shut up.”
